Abstract

The invention discloses a self-cooling type solid desiccant cooling dehumidification air-conditioning system. The air-conditioning system comprises a cooling dehumidification system and a heating regeneration system which are connected with each other. Dehumidifying heat exchangers formed by enabling solid dehumidifying materials to be attached to surfaces of finned tube type heat exchangers independently performing sensible heat exchange traditionally are adopted in the cooling dehumidification system and the heating regeneration system. Dehumidifying turning wheels are replaced by the dehumidifying heat exchangers. In the dehumidification process, chilled water generated by regenerating evaporating cooling is led into the dehumidifying heat exchangers, so that a self-cooling type low temperature inner heat source is formed, and cooling is carried out in the desiccant dehumidification process; in the regenerating process, hot water generated through low-grade heat energy serves as a heating inner heat source to be led into the desiccant desorption process; and by switching the dehumidification process and the regenerating process, thermodynamic cycle for continuous refrigeration is achieved. Compared with a dehumidifying turning wheel system, the self-cooling type solid desiccant cooling dehumidification air-conditioning system not only has the advantages of being small in size and low in cost, but also can achieve the self-cooling type cooling dehumidification process, and the efficiency of the whole system is greatly improved.

Description

Self-cooled solid drier cool-down dehumidification air-conditioning system
Technical field
The present invention relates to the system in a kind of refrigeration and air-conditioning technical field, specifically a kind of self-cooled solid drier cool-down dehumidification air-conditioning system.
Background technology
In recent years, along with the frequent appearance in all parts of the world of the raising of people's living standard and extreme environment, widely used traditional vapor compression heat pump air-conditioning system has become the main source of entire society's power consumption.Causing the main cause that conventional compression formula air conditioning energy consumption is higher is that system adopts the air-treatment method of dehumidification by condensation to focus on sensible heat and latent heat load.Solid dehumidifying air-conditioning technical adopts natural refrigerant-water as cold-producing medium, based on solid drier, the suction-operated of steam is processed to airborne latent heat load and realize dehumidifying, then by vapor cooling system, process airborne sensible heat load and realize cooling, system realized separately processing of sensible heat load and latent heat load and independent control, overcome the limitation that compressed air conditioner technology focuses on load.Due to the hot reproducing characteristic of drier, system can adopt the even low grade heat energy drivings such as condensation heat extraction of compression system of solar energy simultaneously.Therefore, solid dehumidifying air-conditioning technical has environmental protection and energy-conservation two large advantages.
In solid dehumidifying air-conditioning system, extensively adopt at present the desiccant wheel that adheres to drier as latent heat load processing unit, sensible heat load is mainly to process by direct or indirect evaporative cooling.Limitation due to desiccant wheel structure, system is in dynamic dehumidification process, because the release of heat of adsorption causes drier and the equilibrium adsorption temperature processed between air improves, drier moisture pick-up properties has increased the wet potential difference of transmitting of heat between dehumidifying and regeneration when declining, the regeneration temperature of circulation demand improves, and whole cycle performance is difficult to improve.On the other hand, the humidification cooling procedure of direct evaporative cooler is had higher requirement to circulating dehumidification ability, causes regeneration temperature to rise, and overall system performance is not high; And the cooling limit minimum temperature of cooling tower indirect evaporation can only arrive the wet-bulb temperature of outdoor air, be difficult to the sensible heat load disposal ability that reaches higher.
Through the open source literature retrieval to prior art, find, for addressing the above problem, Chinese Patent Application No. is " can utilize the two-stage rotating wheel dehumidification air conditioner device of low-grade heat source " patent of 200710045901.2, be by the cooling two stage dehumidify flow scheme design of inter-stage, realize intercooled solid dehumidifying process, although compare with legacy system, two stage dehumidify performance increases, yet system cannot realize inner-cooled dehumidifying, sensible heat load disposal ability is still not enough simultaneously, Chinese Patent Application No. is " air-conditioning system that high temperature heat pump and desiccant wheel and high temperature heat pump are coupled " patent that 201110356517.0 " composite air conditioner system of a kind of air source heat pump and rotary wheel dehumidifying combination " and Chinese Patent Application No. are 200810052297.0, be all by a compression heat pump circular treatment sensible heat load and part rotary wheel regeneration heat is provided, although obtaining, the sensible heat load disposal ability of system improves, yet owing to still having adopted traditional compressed air conditioner in system, system cannot overcome the cold-producing medium use that environment is existed to impact, simultaneity factor itself exists volume larger, complex structure, the deficiency that cost is higher.
